Chapter 6. Remotely Creating Data Grid Caches

Procedure

1. Navigate to <server_hostname>:11222/console/ in any browser.
2. Log in to the console.
3. Open the Data Container view.
4. Select Create Cache and then add a cache from a template or with Data Grid configuration in XML or JSON format.
5. Return to the Data Container view and verify your Data Grid cache.

Procedure

1. Create a CLI connection to Data Grid.

2. Add cache definitions with the create cache command.

   • Add a cache definition from an XML or JSON file with the --file option.

     [//containers/default]> create cache --file=configuration.xml mycache

Procedure

1. Configure your client with the ConfigurationBuilder class.

   import org.infinispan.client.hotrod.RemoteCacheManager;
   import org.infinispan.client.hotrod.DefaultTemplate;
   import org.infinispan.client.hotrod.configuration.ConfigurationBuilder;
   import org.infinispan.commons.configuration.XMLStringConfiguration;
   ...
   
   ConfigurationBuilder builder = new ConfigurationBuilder();
   builder.addServer()
            .host("127.0.0.1")
            .port(11222)
          .security().authentication()
             .enable()
             .username("username")
             .password("password")
             .realm("default")
             .saslMechanism("DIGEST-MD5");
   
   manager = new RemoteCacheManager(builder.build());

2. Use the XMLStringConfiguration class to add cache definitions in XML format.

3. Call the getOrCreateCache() method to add the cache if it already exists or create it if not.

   private void createCacheWithXMLConfiguration() {
       String cacheName = "CacheWithXMLConfiguration";
       String xml = String.format("<infinispan>" +
                                     "<cache-container>" +
                                     "<distributed-cache name=\"%s\" mode=\"SYNC\"
                                     statistics=\"true\">" +
                                       "<locking isolation=\"READ_COMMITTED\"/>" +
                                       "<transaction mode=\"NON_XA\"/>" +
                                       "<expiration lifespan=\"60000\" interval=\"20000\"/>" +
                                     "</distributed-cache>" +
                                     "</cache-container>" +
                                   "</infinispan>"
                                   , cacheName);
       manager.administration().getOrCreateCache(cacheName, new XMLStringConfiguration(xml));
       System.out.println("Cache created or already exists.");
   }

4. Create caches with org.infinispan templates as in the following example with the createCache() invocation:

   private void createCacheWithTemplate() {
       manager.administration().createCache("myCache", "org.infinispan.DIST_SYNC");
       System.out.println("Cache created.");
   }
